A toy seller gives a 20% discount on MRP on each toy and if a boy bought 45 toys at discounted price, he will also get 15 toys free. Even after selling 60 toys on the price of 45, toy seller earns 20%.
16.Question
Find ratio of MRP of 1 toy to Cost price [for toy seller] of 1 toy.
(a) 4 : 1
(b)10 : 1
(c) 5 : 1
(d) 3 : 1
(e) 2 : 1
Answer :- E
Explanation :-
Let the MRP of each toy is Rs. 100.
Therefore, Selling price of each toy is Rs. 80.
When customer paid Rs. 80 × 45 = Rs. 3600
the toy seller will give him(the boy) 60 toys i.e. at a price of Rs. 60/toy
Even on this SP of Rs. 60, the toy seller earns 20%
Therefore, CP of 1 toy = 60 × 100/120 = Rs. 50
Required ratio = 2 : 1
Thus, the ratio between the MRP and CP of 1 toy = 2 : 1
17.Question
A man paid price for 60 toys and a woman paid the price for 90 toys. Average price per toy paid by the man is how much % more than that of the woman.
a) 5.25 %
b) 6.66 %
c) 9 %
d) 11.30 %
e) 15 %
Answer :- B
Explanation :-
When the man will pay for 60 toys, he will get 60 toys at a price of 45 and then 15 more balls at 20% discount.
And When the woman will pay for 90 toys she will get 120 balls. i.e. 15 free for every 45 balls.
The man will pay 60×80 = Rs 480 for 75 toys =Rs.6.4 / toy
While the woman will pay Rs 90 ×80 = 720 for 120 toys
= Rs. 6 / toy
Required % = (6.4 – 6)/6 × 100 %
= 6.66 %
Thus the required more percentage paid by man = 6.66 %
18.Question

Profit of first trader = 900 × 1/3 = 300
Thus, the required profit of the first trader = Rs. 300
21.Question
A fruit seller allows 4% discount and allows 2 apple free on purchase of 14 apple . He earns 40% profit on the transaction. By what percentage above the cost price he marked price of the Apple ?
(a) 55.50%
(b) 33.33%
(c) 66.66%
(d) 50%
(e) None of these
Answer :- C
Explanation :-
Let, cost price (CP) of one apple = 100x
14 × SP = 16 × CP + 40% of CP of 16 apple [SP → Selling price]
14 × SP = 1600x + 40/100 × 1600x
14 × SP = 2440x
SP = 160x
SP = 96% of MP [MP → marked price].
MP = 160x / 96 × 100
= 500x / 3
Required percentage
= (500x/3 – 100x ) / 100x × 100%
= 66.66 %
Thus, required more percentage of the marked price above the cost price = 66.66 %

Study the following information carefully and answer the questions given below. In a cricket tournament , probability that A team will win this match is 1/2 and the probability that B team will win this match is 1/3.
22.Question
What is the probability that both A and B team will win this match?
a) 1
b) 1/6
c) 2/3
d) 1/3
Answer :- B
Explanation :-
Probability that A team win the match = 1/2
Probability that B team will win the match = 1/3
Probability that both team will win the match = Probability that A team will win and probability that B team will win
= 1/2 x 1/3
= 1/6
Thus, the probability that both A and B team will win the match =1/6
23.Question
What is the probability that only 1 team [either A team or B team] will win the match?
1. 1/2
2. 1/3
3. 1/7
4. 2/3
Answer:- A
Explanation :-
Probability that A team will win the match = 1/2
So, Probability that A team will loss the match = 1/2.
Probability that B team will win the match = 1/3
So, Probability that B team will loss the match = 2/3.
Probability that only one person will win is when A team wins and B team loss or A team loss and B team win.
= (1/2) x (2/3) + (1/2) x (1/3)
= 1/3 + 1/6
= 1/2
Thus, the probability that only one team will win = 1/2
24.Question
Three labors A, B, C can do a work in 15 days, if they working together. But B can work only half time due to his illness. The work can be finished in how many days?
(a) 16 days
(b) 17 days
(c) 18 days
(d) 20 days
(e) None of these
Answer :- C
Explanation :-
Let, efficiency of each labor is 1 unit/day
For three labors, it is 3 units/day
Hence in 15 days, Total work to be done = 45 units
If B works for half a day only
Then total work in a day by three worker = 1+ 1 + 0.5 = 2.5
Hence, No. of days required to finish = 45/2.5 days = 18 days
25.Question
A shopkeeper marks his goods at a certain price. He allows a discount on marked price is 8 % and still he gains 15 % . At what percent above the cost price does he marks in his goods?
(a) 28
(b) 35%
(c) 22
(d) 25%
(e) None of these
Answer :- D
Explanation :-
Let, Marked price (MP) = 100
Selling price ( SP) = (100 – 8) = 92
Cost price ( CP) = 92 × 100/115 = 80
MP – CP = (100 – 80) = 20
Required % = 20/80 × 100 %
= 25 %
Thus, the required percentage above the cost price, he marks his good = 25 %
26.Question
Rs. 40 is the difference between the compound interest and the simple interest on a certain sum for two years, when the interest is compounded yearly .The rate is 10 % . If the interest is compounded half-yearly, what will be the difference between the
CI and the SI ?
(a) Rs 40
(b) Rs 52.550
(c) Rs 62.025
(d) Rs 64.50
(e) Rs 72.0125
Answer :-C
Explanation :-
Difference = Principal ×( r/100) ^2
=> Principal = difference × ( 100/r) ^2
=> principal = (40 × 100 × 100)/(10× 10)
= 4000
When interest is compounded half yearly ,
T = 4
r = 10/2 = 5 %
P = 4000
Amount = 4000 ×(1+ 5/100) ^4
= 4862.025
Compound interest (CI) = Amount – Principal
= 862.025
Simple Interest ( SI) = 4000 × 10 × 2 /100
= 800
Difference = CI – SI =( 862.025 – 800 ) = 62.025
Thus, the difference between the compound interest and simple interest =Rs.62.025

=> h^2 = 576
=> h = 24 metre.
Volume = 1/3 πr^2h
= 1/3 ×22/7 × 7 × 7 × 24
= 1232 m3
Thus, the volume of the circular Cone is = 1232 metre3

A person is working in a company . Savings of the person is 10% of his total income. After promotion his income is increased by 20% but his savings remain the same. Find the hike percentage in his expenditure .
(a) 23.65%
(b) 22.95%
(c) 22.22%
(d) 15.95%
(e) None of these
Answer :- C
Explanation :-
In first case,
Let, Income = 100
Savings = 10
Expenditure = (100 – 10) = 90
In second case,
Income = 120
Savings = 10 ( savings remain same)
Expenditure =( 120 – 10 )= 110
Hike % in expenditure = (110 – 90) /90 × 100 %
= 22.22 %
Thus, the hike percentage of expenditure of the person = 22.22%
30.Question
The rate of the current is 3 km/h and upstream speed of a motorboat is 5 km/h, then how much time taken to cover a distance 55 km in downstream ?
(a) 3 h
(b) 5 h
(c) 4 h
(d) 4.5 h
(e) None of these
Answer :- B
Explanation :-
Rate of current = 3 km/h
Upstream speed(U) = 5 km/h
Rate of current = 1/2 ( downstream speed – upstream speed)
=> 1/2 ( D – U) = 3
=> D – 5 = 6
=> D = 11 km/h
Downstream speed = 11 km/h
Time taken = 55/11 = 5 h
Thus, the time taken to cover the distance in downstream = 5 hour

For 2010 and 2011 = 50 – 30 = 20.
For 2014 and 2015 = 80 – 80 = 0.
For 2010 and 2013 = 50 – 30 = 20.
For 2013 and 2014 = 80 – 50 = 30.
For 2015 and 2016 = 80 – 60 = 20.
Thus, the maximum difference is between the years 2013 and 2014 .
33.Question
If the number of passengers qualified in 2014 was 21200, what was the number of passengers applied in 2014?
